In this episode of MASS Office Hours, Dr. Eric Trexler and Dr. Mike Zourdos answer questions submitted by listeners and viewers in the live chat. Topics include Progressive overload strategies, zone 2 cardio and interference effect, the importance of rest days, doing velocity work during rest periods, stretch-induced hypertrophy with low loads, specialization blocks, eccentric versus concentric training, creatine and sleep quality, the importance of carbohydrate, and much more.
